AI Technical Summary

Technical Problem

In the existing technology, it is difficult for equipment control systems to ensure the safety of synchronous processing under non-fixed periodic communication, especially when the communication network fluctuates, it is difficult to maintain the reliability of fixed periodic communication.

Method used

By acquiring non-fixed-period communication data between the local device and the controller, it determines whether a synchronization error has occurred and performs corresponding error handling when an error occurs, including stopping the device or outputting a warning message, to ensure the safety of the system.

Benefits of technology

Under non-fixed-period communication conditions, the error handling mechanism can effectively maintain the synchronous processing safety of the equipment control system and prevent system instability caused by synchronization errors.

Abstract

The device control system of one aspect of the present disclosure includes: an acquisition unit that acquires communication data transmitted through non-fixed period communication between a local device and a controller that controls the local device; a determination unit that determines whether a synchronization error has occurred based on the communication data, the synchronization error being an error related to synchronization between the local device and the controller; and an error processing unit that performs error processing associated with at least one of the local device and the controller in a case where the synchronization error has occurred.
